Section VI - General Disassembly / Reassembly
WARNING:
Always make sure the power cord is unplugged and the battery is removed before attempting to perform any installation or
removal procedures.
• Follow ESD (Electrostatic Discharge) safety procedures to protect the electronics located within the controller.
• Remove the power cord cover by first removing the retaining screw on the cord cover door.
• Slide the cord cover door off by pressing the door to the right.
• Remove the power cord by rocking back and forth until the cord is loose.
• Remove the five (5) screws that hold the front cover to the rear cover with a Phillips head screwdriver.
• The front cover may now be carefully pulled away. To separate the front and rear covers, reach in and remove the transducer tube from the transducer
on the front cover. (Diagram 01)
• Observe and note the locations of all tubing and wiring harnesses for ease in reassembly.
• If required, disconnect the electrical connectors and tubes so the two case halves can be separated completely.
• Reassembly is the reverse of disassembly.
Battery Pack (Removal / Installation)
• Remove the battery pack screw located on the bottom center of the rear case of the controller.
• Slide the battery pack out by pulling on the tab on the bottom, right side of the unit.
• Installation is the reverse of removal.
Compressor (Removal / Installation)
• The compressor is not a user serviceable component. Do not disassemble. Do not oil. The compressor is mounted to its own separate bracket that, in
turn, mounts through the inside of the battery compartment in the rear case of the controller.
• Disconnect the pump wiring harness from the Controller Board on the front case.
• Disconnect the compressor output tube at the check valve. (Diagram 02)
• Remove the compressor intake tubing from the muffler port. (Diagram 02)
• Remove the two (2) screws from the compressor mounting bracket. (Screws are accessible through the right side battery compartment once the
battery pack is removed.) (Diagram 01)
• Slide the entire compressor assembly out of the rear case housing.
• Installation is the reverse of removal.
Valve Manifold and Bed Hook (Removal / Installation)
• The valve manifold is located in the center of the controller on the rear case. It is a plastic manifold block with six solenoid valves. No attempt should
be made to repair a damaged manifold or valve. Return the entire assembly for repair or replacement.
• Inspect tubes that lead to the manifold for kinks and proper attachment before performing any work. Detach all tubing from the manifold fittings.
Note the location of connections and the tubing routing for ease of reassembly.
• Disconnect the valve wiring harness from the Controller Board on the front case.
• Remove the two side screws from the valve manifold assembly and then pull the bed hook away from the rear case. (Diagram 03)
• Remove the center screw from the manifold assembly and remove the valve manifold.
• Some wires may be secured to the manifold with wire ties. Be prepared to reattach these wires after reinstalling the assembly. New wire ties will be
required.
• Installation is the reverse of removal.
Muffler (Removal / Installation)
• The muffler is a custom plastic part used to keep the Kendall SCD EXPRESS Compression System running quietly.
• To remove the muffler detach the compressor intake tubing and slide the muffler out from under the power board.
• For reinsertion of the muffler be sure to route the intake tubing properly. (Diagram 02) Tubing must be run between the muffler and the right side of
the rear case to avoid kinking.
